 the metal layer contacts the conductive film through each of the contact holes, in the frame area. 
 
     
     
       2. The display device according to  claim 1 ,
 further comprising an organic insulating film on the insulating film, 
 wherein 
 the organic insulating film covers an edge of the pixel electrode and has an opening above each of the contact holes, and 
 the metal layer contacts the conductive film through the opening. 
 
     
     
       3. The display device according to  claim 2 ,
 wherein the organic insulating film doesn't extend to an edge of the substrate. 
 
     
     
       4. The display device according to  claim 1 ,
 wherein the display area and each of the contact holes are surrounded by a sealant. 
 
     
     
       5. The display device according to  claim 4 ,
 wherein the sealant covers an edge part of the transparent conductive layer and an edge part of the metal layer. 
 
     
     
       6. The display device according to  claim 1 ,
 wherein the contact holes are individually formed at a plurality of places in the frame area. 
 
     
     
       7. The display device according to  claim 1 ,
 further comprising a data signal driver circuit on the substrate, 
 wherein 
 the data signal driver circuit is located along a side of the display area, and 
 the conductive film extends along another side of the display area. 
 
     
     
       8. The display device according to  claim 1 , wherein
 the metal layer is configured to be light-permeable from the light emitting material in the display area. 
 
     
     
       9. A display device comprising:
 a substrate having a display area and a frame area surrounding the display area, 
 the display area comprising: 
 a pixel electrode on the substrate; 
 an organic insulating layer covering an edge of the pixel electrode and exposing an upper surface of the pixel electrode; 
 an organic layer including a light emitting material and covering the upper surface of the pixel electrode; 
 a metal layer covering the organic insulating layer and the organic layer; and 
 a transparent conductive layer covering the metal layer and overlapping the organic insulating layer and the organic layer, 
 wherein 
 the frame area comprises a conductive film covered by the organic insulating layer, 
 the organic insulating layer has openings exposing a surface of the conductive film, 
 the metal layer and the transparent conductive layer extend from the display area to the frame area, and cover the openings, and 
 the metal layer is connected to the conductive film at the openings. 
 
     
     
       10. The display device according to  claim 9 ,
 wherein the organic insulating layer doesn't extend to an edge of the substrate. 
 
     
     
       11. The display device according to  claim 9 , wherein
 the display area and each of the openings are surrounded by a sealant. 
 
     
     
       12. The display device according to  claim 11 ,
 wherein the sealant covers an edge part of the transparent conductive layer and an edge part of the metal layer. 
 
     
     
       13. The display device according to  claim 9 ,
 wherein the openings are individually formed at a plurality of places in the frame area. 
 
     
     
       14. The display device according to  claim 9 ,
 wherein the metal layer is configured to be light-permeable from the light emitting material at the display area.
